Your Slow Smart TV Doesn’t Need Replacing. It Needs a Debloat
Our TCL Roku TV had gotten painfully slow. We didn’t replace it. We debloated it in about 20 minutes, and it’s noticeably faster.
Budget smart TVs ship with very little memory, and then the software fills it up: ad tracking, animated themes, promoted rows and every app you installed once and forgot about. Here’s exactly what we changed on a TCL 40S325 running Roku OS 16.0.4, what made the biggest difference, and how the same idea works on Samsung, LG, Sony and Vizio TVs.
One honest note up front: we didn’t run benchmarks. “Faster” here means the home screen, menus and app launches stopped lagging in everyday use. Your results will depend on your model.
1. Turn off the feature that watches your screen
Most smart TVs use automatic content recognition (ACR). It samples what’s on screen, including what’s coming in from your game console or cable box, and reports it for advertising. On a Roku TV it’s called Smart TV Experience.
- Roku TV: Settings → Privacy → Smart TV experience → uncheck Use info from TV inputs.
This was the single biggest change on our TV. Turning it off doesn’t delete data that was already collected, according to Roku TV manuals, but it stops collection going forward. ACR is under legal pressure too: in March, Malwarebytes reported that Samsung settled with Texas and agreed to stop collecting ACR data from Texans without explicit consent. The state had also sued Hisense, Sony, LG and TCL.
2. Limit ad tracking
Go to Settings → Privacy → Advertising. Turn off personalized ads (older Roku versions call it Limit ad tracking, which you check instead) and reset your advertising ID. How-To Geek explains that this stops Roku using your viewing data for targeted ads. It does not reduce the number of ads, and Roku notes that individual apps can still collect their own data.
3. Strip the home screen down
- Theme: Settings → Theme. Swap animated wallpapers for a plain one, and set the screensaver to a simple clock or none.
- Menu items: Settings → Home screen. Hide Live TV, Featured Free, What to Watch and Sports if you don’t use them. PCWorld walks through the options.
- Fast TV Start: Settings → System → Power. It makes the TV come on faster, but BGR notes it uses more power in standby.
4. Delete the apps you don’t use
Our TV had 33 apps installed, including duplicates like two separate Showtime apps and a “Kids & Family” version of The Roku Channel. To remove one, highlight it on the home screen, press ✱ and choose Remove app.
This helped, but less than the settings did. Unused apps mostly cost storage and background updates, not constant memory.
5. Restart it
The official way is Settings → System → Power → System restart. There’s also a widely shared remote shortcut: Home five times, Up, Rewind twice, Fast Forward twice. Tom’s Guide and others call it a cache clear. We could only confirm that it restarts the TV, so treat it as a quick reboot. Don’t confuse it with Home ×5, Fast Forward ×3, Rewind ×2, which opens a hidden menu that includes a factory reset option.
6. Block ads for the whole house
For a network-wide filter, set your router’s DNS to AdGuard DNS, which is free: 94.140.14.14 and 94.140.15.15. On Google or Nest Wifi, that’s in the Google Home app under Wi-Fi → Network settings → Advanced networking → DNS. It blocks known ad and tracking servers for every device in your home, not just the TV. If something stops working, set DNS back to automatic.
Be realistic about what’s left. The big banner ad on Roku’s home screen comes from the same servers as the home screen itself, and ads inside YouTube, Hulu, Tubi or The Roku Channel come from the same servers as the shows. No TV-side blocker removes those. Only paying for an ad-free plan does.
What made the difference
| Change | Effect on our TV |
|---|---|
| ACR off, ad tracking limited | Biggest improvement |
| Plain theme, hidden menu items | Smoother home screen |
| Removed unused apps (33 installed) | Small improvement |
| Restart | Helps right away, wears off over time |
| AdGuard DNS | Fewer trackers on every device; home screen and in-app ads remain |
It works on other TVs too
Every major brand has its own name for ACR. These paths come from Malwarebytes’ guide, and menus move around between model years:
| Brand | Setting to turn off | Where to find it |
|---|---|---|
| Roku TV (TCL, Hisense and others) | Use info from TV inputs | Settings → Privacy → Smart TV experience |
| Samsung | Viewing Information Services | Settings → Support → Terms & Privacy → Privacy Choices |
| LG (webOS) | Live Plus | Settings → All Settings → General → System → Additional Settings |
| Vizio | Viewing Data | Menu → System → Reset & Admin |
| Sony (Google TV) | Samba Interactive TV | Settings → All Settings → Privacy |
Samsung also offers Interest-Based Advertising and Voice Recognition Services in the same menu, and LG has its own Limit Ad Tracking option. The rest of the checklist works on any brand: remove apps you don’t use, turn off animated extras, restart now and then, and filter ads at the router.
Samsung Frame owners: meet CleanFrame
If you’d rather replace the cluttered home screen entirely, CleanFrame is an open-source project by developer nthnclrk that swaps Samsung’s busy interface for a quiet one: your apps, a photograph and the time, made for the TV remote. You can pick a List or Dock layout, choose from fifteen wallpapers, reorder your apps and switch HDMI inputs from its settings.
- Built for: Samsung The Frame on Tizen, with an installation minimum of Tizen 5.0. Owners have reported it working on other Samsung models, such as the Q60B and AU8000, in their own adapted builds, listed in the project’s compatibility notes.
- Not plug-and-play: you enable Developer Mode on the TV, build it yourself and sign it with your own Samsung certificates. The release download is unsigned and isn’t ready to install.
- The risky part: making the remote’s Home button open CleanFrame is a separate, optional step that uses undocumented settings and can break after a firmware update. You can open CleanFrame like a normal app without doing it.
- Status: version 0.7.0 came out November 2, the code is MIT-licensed, and the repo had about 950 GitHub stars when we checked on November 4.
The developer says plainly that it’s built for their own TV and that you use it at your own risk. They recommend trying the browser preview first and working with a coding agent if you adapt it. It doesn’t run on Roku, LG or Google TV; each of those would need its own implementation.
PCGeek’s take
Before you buy a new TV because the old one feels slow, spend 20 minutes in Settings. The tracking features you never asked for are the first thing to turn off, and on our budget Roku TV they made more difference than deleting apps. You won’t get rid of every ad, because the platforms are built around them. But you can get a TV that responds when you press a button, and that’s worth an evening.
Have you debloated your smart TV, and which setting made the biggest difference for you?
